ChatGPT is OpenAI's flagship AI assistant — GPT-5 chat with web, voice, image generation, code interpreter, and custom GPTs. Powered by OpenAI's GPT-5 model with multimodal understanding across text, image, and voice inputs.
What it does well
- Powered by OpenAI's GPT-5 model with multimodal understanding across text, image, and voice inputs.
- Supports web browsing, image generation, and a built-in code interpreter for executing Python within chat.
- Allows users to build and share custom GPTs tailored to specific tasks or domains.
- Available as a web app and native desktop and mobile clients for macOS, Windows, iOS, and Android.
Where it falls short
- Free tier imposes message caps, slower response times during peak hours, and limited access to the most advanced models.
- Closed-source platform that cannot be self-hosted or run on local models.
- No support for third-party model providers such as Claude or Gemini within the core ChatGPT product.

Concepts you should know
- Chain of thought
Asking an LLM to spell out intermediate reasoning steps before producing the final answer. Improves accuracy on multi-step problems by ~10-30 percentage points on most reasoning benchmarks.
- Citation
When a generative-search system attributes part of its answer to a specific source URL, usually with a footnote-style number or an inline link. The visible signal that a brand was used to ground a model's answer.
- Reasoning token
Tokens spent by a reasoning model (o-series, DeepSeek R1, Claude with extended thinking) on hidden chain-of-thought before the visible answer. Billed separately at the same rate as output tokens. Can be 10-100× the visible-answer length on hard problems.
